I need help from Text Classifier

Hi everyone,

I need advice on how to use n8n’s Text Classifier node. I have some questions about the node’s configuration. What are the differences between the Text to Classify label and the System Prompt Template?
For example:
Text to Classify has redirected the various Categories, which are then divided into other nodes that sort by subcategories.
System Prompt Template, on the other hand, I write the desired output of the node and the various aliases to help the LLM understand which category it is.
Actually, the output and aliases are in both nodes.

Do you have any suggestions for improving the flow? In fact, it doesn’t recognize the various categories/subcategories very well.

I attach the screen capture of the stream (still to be finalized):
